Yea, its the same stuff, just grey and not black. Believe me, I don't mind all the blocking, I actually kinda enjoy it... I guess I'm wierd like that. :-)

What about the fine cracks in the front urethane nose? Can I just skim it over with flexible filler or do I need to get more extreme with it? The chances of finding another nose in better shape are pretty slim

Depending on how fine the cracks are,and are they cracks in the existing paint or the bumper cover and what kind of flexible filler...What where you planning on using?
